Hi gxt15
Sorry for delay. I was upo to some other issue and forget to post suggestioon here.
So try these:
Use body class in css.
Home pages in WP have either “home” or a particular template used name (whatever you choose to be the home page) in the body class.
As such, you can create CSS for “display:block” and “display:none” so that images only show up on or don’t show up on pages that match that body class.
Body Class Reference CSS
So concerning your pages/posts:
Try put this to your style css plugin file
.site-header {
background: none;
}
body.archive.category.category-home.category-21.site-header {
background-image:url('https://www.genxtraveler.com/wp-content/uploads/2015/09/cropped-2015-07-27-00.28.301.jpg') ;
}
Hope this will be helpfull ??

You can also do this with PHP, if you put in a conditional statement in the header.php file of your child theme to select whichever block you want. See:
Function Reference/is front page
Have a fun
Cheers
